Sunitinib is a kinase inhibitor present in sunitinib malate capsules as the malate salt. Sunitinib malate is described chemically as N-[2-(Diethylamino)ethyl]-5-[(Z)-(5-fluoro-1,2-dihydro-2-oxo-3H-indol-3-ylidene)methyl]-2,4-dimethyl-1H-pyrrole-3-carboxamide, compound with (S)-2-hydroxybutanedioic acid. The molecular formula is C 22 H 27 FN 4 O 2 .C 4 H 6 O 5 and the molecular weight is 532.57 Daltons. The chemical structure of sunitinib malate is: Sunitinib malate is light yellow to brownish orange colored powder with a pKa of 8.95. The solubility of sunitinib malate in aqueous media over the range pH 1.2 to pH 6.8 is in the range of 12 to 70 mg/mL. The log of the distribution coefficient (octanol/water) at pH 7 is 5.2. Sunitinib malate capsules are supplied as printed hard shell capsules containing 12.5 mg, 25 mg, 37.5 mg or 50 mg of sunitinib (equivalent to 16.7 mg, 33.4 mg, 50.1 mg, or 66.8 mg of sunitinib malate, respectively) together with croscarmellose sodium, magnesium stearate, mannitol and povidone (K-30) as inactive ingredients. The reddish brown gelatin capsule shells contain ferric oxide red and titanium dioxide. The caramel gelatin capsule shells contain ferric oxide red, ferric oxide yellow, ferrosoferric oxide and titanium dioxide. The yellow gelatin capsule shells contain ferric oxide yellow and titanium dioxide. The white printing ink contains potassium hydroxide, shellac and titanium dioxide. The black printing ink contains ferrosoferric oxide, potassium hydroxide and shellac. spl-sunitinib-malate-structure
